Objective To investigate the protective effect of Xinyi capsule pretreatment on myocardial ischemia reperfusion injury in rabbits and its possible mechanism. Methods Ninety-four rabbits were randomly divided into 6 groups: model group (n=16), tirofiban group (n=16), high-, medium- and low-dose Xinyi capsule groups (4.0, 2.0, 1.0 g/kg;n=16 in each group), and sham operation group (n=14). Five days after intragastric administration with drug, myocardial ischemia reperfusion was induced by ligation of the proximal left circumflex artery. The electrocardiogram (ECG) was continuously recorded. The serum levels of myeloperoxidase (MPO), lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) were measured. Myocardial histopathological damage was evaluated. Results The changes of J-point amplitude on ECG in high-, medium-and low-dose Xinyi capsule groups (0.064 ± 0.049 mV, 0.069 ± 0.061 mV, 0.079 ± 0.060 mV) were significantly lower than that in the model group (0.158 ± 0.105 mV, P<0.01 or P<0.05), the serum levels of LDH (399.7 ± 202.3 U/L, 369.6 ± 229.0 U/L, 435.5 ± 152.4 U/L), CK-MB (900.8 ± 231.2 U/L, 1 268.3 ± 899.8 U/L, 1 386.7 ± 621.6 U/L), MPO (69.81 ± 5.51 U/L, 85.44 ± 10.31 U/L, 81.33 ± 16.87 U/L) were significantly lower than those in the model group (LDH:817.1 ± 401.9 U/L, CK-MB:2 071.3 ± 693.5 U/L, MPO:149.9 ± 20.11 U/L;P<0.01 or P<0.05). Histopathological examination showed that myocardial damage in high-, medium- and low-dose Xinyi capsule groups reduced compared with the model group. Conclusions Xinyi capsule pretreatment can protect against myocardial ischemia reperfusion injury in rabbits, and its mechanism may be related to inflammation inhibition.

OBJECTIVETo study the rules of occurrence and development of TCM syndromes in patients of depression by analysing the population distribution and related factors of it.

METHODSA clinical epidemiologic survey was carried out with the materials collected by the four-diagnostic method from patients of depression to gain the syndrome types of 397 patients through dynamic cluster analysis, factor analysis and TCM syndrome differentiation. The constitution of syndrome types in different population and the relation between TCM syndrome types and the clinical types differentiated by Western medicine of depression was analyzed.

RESULTSSix syndrome types were found in 397 patients with depression. They were, ranging in occurrence order, the Gan-Qi stagnation with mental uneasiness type (108 cases, 27.2%); the Xin-Pi deficiency with dampness retention type (94 cases, 23.7%); the Xin-Gan Qi-stagnation with Phlegm retention type (76 cases, 19.1%); the Xin-Gan Qi stagnation with Jing-Luo disharmony type (57 cases, 14.3%); the Xin-Shen Qi stagnation with collateral obstruction type (34 cases, 8.6%); and the Xin-Gan Qi stagnation with Heat interfering mental type (28 cases, 7.1%). There were statistical significance (P < 0.01) in comparison of the syndrome types constitution among patients of different ages or different Western medicinal types (mild, with or without psychotic symptoms), but no significant difference was shown in that among patients of different sexes, with or without familial history of mental diseases, with monophasic or biphasic, initial or recurrent episode (P > 0.05).

CONCLUSIONThe result obtained in this study is basically in accord with the cognitive rule of TCM theory, it provides a reliable base of syndrome differentiation for treatment.

Objective To observe prospectively and systematically the effect and safety of rhendostati injection (endostar) combined with FOLFOX as a second line chemotherapy for advanced/metastatic colorectal cancer. Methods 23 patients with histological confirmed advanced/metastatic colorectal cancer after first line chemotherapy failure were observed. The dosage of 15 mg/time of endostar solved in 500ml normal saline was slowly intravenously dropped 4 h from day 1 to day 14. Oxaliplatin 85 mg/m~2 iv 2-3 h dl, d15. CF 200 mg/m~2 iv 2 h followed by 5-Fu 400 mg iv bolus and 5-Fu 600 mg/m~2 iv 22 h dl-2, d15-16 were given, every 4 weeks as one cycle. Efficacy was evaluated after 2 cycles according to RECIST criteria. Results 23 cases had been completed totally 56 cycles. Among 23 cases, 8 cases were PR, 12 cases SD, and 3 cases PD. The objective response rate (RR) was 34.8 % (8/23), and the disease control rate (DCR) was 87.0 % (20/23). The median time to progression was 7 months. The 1-year survival rate were 50.0 %. The 2-year survival rate was 40.0 %. The occurrence rate of G3/4 toxicities was low, including neutropenia(21.7 %), anemia(4.3 %), thrombocytopenia (13.0 %). Those toxicities were mainly related with the chemotherapy agents. Meanwhile transient electrocardiogram changes mild ST-T of changes occurred in 3 cases. 2 cases were mild hypertension and were symptomatically controlled. Conclusion There are better efficacies of endostar combined with FOLFOX chemotherapy for advanced/metastatic colorectal cancer, and it is low toxic and tolerable. It is worth of further clinical observation. More experiences need to be accumulated.

OBJECTIVETo investigate the incidence of testicular appendages, observe their morphology, and analyze their histopathological origins.

METHODSWe observed 67 testes in 54 patients (15 children and 39 adults) undergoing scrotal surgery, investigated the incidence of testicular appendages, and identified their histopathological origins. We used the Chi-square test to compare the findings from the children and adult patients, with P < 0.05 as statistically significant.

RESULTSThe detection rates of the appendix testis, appendix epididymis, paradidymis, vas aberrans superior, and vas aberrans inferior were 80.6% (54/67), 23.9% (16/67), 1.5% (1/67), 3.0% (2/67), and 1.5% (1/67), respectively. The incidence of testicular appendages was higher in children than in adults (93.3% vs 80.8%), but with no statistically significant difference (Chi2 = 1.339, P > 0.05), and that of the appendix testis and epididymis with pedicles was significantly higher in the former than in the latter (82.4% vs 54.7%, chi2 = 4.149, P < 0.05). Pathological examination showed that the appendix testis originated from the paramesonephric duct, while the appendix epididymis, paradidymis, vas aberrans superior, and vas aberrans inferior from the mesonephric duct.

CONCLUSIONTesticular appendages consist of five embryonic remnants, including appendix testis, appendix epididymis, paradidymis, vas aberrans superior, and vas aber- rans inferior. The appendix testis originates from the paramesonephric duct, and the other four from the mesonephric duct. The clinical implication of these testicular appendages is their tendency to torsion.

Objective To observe the expression of human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA125) in endometrial carcinoma(EC) tissues,and to explore the relationship between the expression of HE4 and CA125 and the occurrence and development of EC.Methods The EC and paracancerous tissue specimens of 35 EC patients were selected from December 2015 to December 2016 in the First People's Hospital of Yibin City.The expression of HE4 and CA125 in EC tissues and paracancerous tissues was detected by immunohistochemistry.The relationship between the expression of HE4,CA125 and the clinicopathological features of EC was analyzed;and the correlation between HE4 and CA125 was analyzed too.Results The positive expression rates of HE4 and CA125 in EC tissues were 82.9％ (29/35) and 74.3％ (26/35);they were 11.4％ (4/35) and 14.3％ (5/35) in paracancerous tissues respectively;the positive expression rates of HE4and CA125 in EC tissues were significantly higher than those in paracancerous tissues(x2 =35.831,25.533;P ＜0.05).The positive expression rates of HE4 and CA125 in stage Ⅲ and Ⅳ EC tissues were 100.0％ (20/20) and 90.0％ (18/20);they were 60.0％ (9/15) and 53.3％ (8/15) in stage Ⅰ and Ⅱ EC tissues respectively;the positive expression rates of HE4 and CA125 in stage Ⅲ and Ⅳ EC tissues were significantly higher than those in stage Ⅰ and Ⅱ EC tissues(x2 =9.655,4.266;P ＜ 0.05).The positive expression rates of HE4 and CA125 in medium and low differentiated EC tissues were 100.0％ (18/18) and 83.3％ (15/18);they were 64.7％ (11/17) and 64.7％ (11/17) in highly differentiated EC tissues respectively;the positive expression rates of HE4 and CA125 in medium and low differentiated EC tissues were significantly higher than those in highly differentiated EC tissues(x2 =7.667,4.137;P ＜0.05).The positive expression rates of HE4 and CA125 in EC tissues with myometrial invasion depth≥ 1/2 were 100.0％ (18/18) and 94.4％ (17/18);they were 64.7％ (11/17) and 52.9％(9/17) in EC tissues with myometrial invasion depth ＜ 1/2 respectively;the positive expression rates of HE4 and CA125 in EC tissues with myometrial invasion depth ≥ 1/2 were significandy higher than those in EC tissues with myometrial invasion depth ＜ 1/2(x2 =7.667,7.884;P ＜ 0.05).The positive expression rates of HE4 and CA125 in EC tissues with lymph node metastasis were 100.0％ (19/19) and 78.9％ (15/19);they were 62.5％ (10/16) and 68.8％ (11/16) in EC tissues without lymph node metastasis respectively;the positive expression rate of HE4 in EC tissues with lymph node metastasis was significantly higher than that in EC tissues without lymph node metastasis (x2 =8.599,P ＜ 0.05),but there was no significant difference in the positive expression rate of CA125 in EC tissues with lymph node metastasis and without lymph node metastasis (x2 =0.473,P ＜0.05).The expression of HE4 and CA125 in EC tissues was not related to age,tumor size and pathological type(P ＜ 0.05).The expression of HE4 in EC tissues was positively correlated with the expression of CA125 (r =0.608,P ＜0.05).Conclusion HE4 and CA125 may be involved in the development and development of EC.The expression of HE4 and CA125 is high in EC tissues,the expression level of them is closely related to clinical stage,histological differentiation and myometrial invasion depth of EC.The high expression of HE4 was also related to lymph node metastasis.

Objective To explore the distribution of dendritic cells (DCs) and the expression of adhesion molecules in rat kidney with unilateral ureteral obstruction (UUO),as well as the regulatory effect of anti-P-selectin lectin-EGF domain monoelonal antibody (PsL-EGFmAb) on adhesion,maturation and function of human DCs cultured in vitro.Methods UUO rat models were established,which were divided into sham group (n=6),untreated group (n=18)and treated group with PsL-EGFmAb(n=18).DCs were analyzed with Axioplan 2 microscopy,while P-selectin being observed by immunohistochemistry.CD34~+ stem cells were isolated from cord blood and cultured in 20%IMDM medium with SCF,GM-CSF,TGF-?1,Flt-3L and TNF-?in vitro.During development, PsL-EGFmAb was added and IL-10 served as control.FACS was performed to detect the expression of HLA-DR,CD1a,CD11c,CD54,CD83,CD80,CD86,CD209 (DC-SIGN) and CD62-P,-E,-L (P-,E-,L-selectin) on DCs.RT-PCR was performed to detect the expression of NF-_KB P50, P65 mRNA.MLR was performed to detect the stimulatory effect of DCs on T cell proliferation and ELISA to determine IL-12p70 amount.Results Comparing with Sham group,the expression of P- selectin was up-regulated among tubulointerstitium mainly on renal tubular epithelial cell after unilateral ureteral obstruction on day 1,while CD1a~+CD80~+DCs being also found in renal interstitium. The expression of P-seleetin and CD1a~+CD80~+DCs was increased evidently on day 7,and correlated with the degree of renal tubulointerstitial fibrosis closely.However,these changes became less conspicuous in rat treated with PsL-EGFmAb.In vitro experiment showed on day 5 after cultured with the induction of TNF-?,immature DCs highly expressed C-type lectin DC-SIGN of pattern recognition receptors;the expression of co-stimulatory molecules such as CD11c,CD83,CD80 and CD86 on mature DCs was up-regulated in paralleling with the mRNA level of NF-_KB;the secretion of IL-12 was enhanced,as well as displaying the features of antigen-presenting cells with a higher ability to induce proliferation of T lymphocytes in vitro.In addition,L-selectin expressed highly on immature DCs,but lowly on mature DCs,neither of two DCs expressed P- and E-selectin.Compared with the IL-10 treated group,PsL-EGFmAb had an inhibitory effect on DC-SIGN of DCs with down- regulating the mRNA level of NF-_KB.PsL-EGFmAb could also inhibited CD11c,CD83,CD80, CD86 expression,reduced secretion of IL-12,and inhibited T cell proliferation stimulated by DCs in vitro.Conclusion DCs may play a critical role on initiating the inflammatory injury of renal tubulointerstitium,and the inhibitory effect of PsL-EGFmAb on DC maturation and function correlated with the inhibition of DC-SIGN,which is mainly mediated through NF-_KB signaling pathway.

BACKGROUNDBreast cancer remains the most important cancer among women worldwide. The disease itself and treatment may have a profound impact on the patients' psychological well being and quality of life. Depression is common in breast cancer patients and affects the therapeutic effects as well as prolongs the duration of hospital stay. However, few studies reported the effectiveness of music therapy on depression and duration of hospital stay of female patients with breast cancer after radical mastectomy.

METHODSOne hundred and twenty subjects were recruited to this clinical trial and randomly allocated to two groups. The experimental group (n = 60) received music therapy on the basis of routine nursing care, whereas the control group (n = 60) only received the routine nursing care. The whole intervention time was from the first day after radical mastectomy to the third time of admission to hospital for chemotherapy. Data of demographic characteristics and depression were collected by using the General Questionnaire and Chinese version of Zung Self-rating Depression Scale (ZSDS) respectively. One pre-test (the day before radical mastectomy) and three post-tests (the day before discharge from hospital, the second and third admission to hospital for chemotherapy) were utilized. Duration of hospital stay was calculated from the first day after radical mastectomy to the day of discharged from hospital.

RESULTSThe mean depression score of all subjects was 37.19 ± 6.30. Thirty-six cases (30%) suffered from depression symptoms, with 26 (72.2%) mild depression cases, 9 (25.0%) moderate depression cases, and 1 (2.8%) severe depression case. After music therapy, depression scores of the experimental group were lower than that of the control group in the three post-tests, with significant differences (F = 39.13, P < 0.001; F = 82.09, P < 0.001). Duration of hospital stay after radical mastectomy of the experimental group ((13.62 ± 2.04) days) was shorter than that of the control group ((15.53 ± 2.75) days) with significant difference (t = -4.34, P < 0.001).

CONCLUSIONSMusic therapy has positive effects on improving depression of female patients with breast cancer, and duration of hospital stay after radical mastectomy can be reduced. It is worthy of applying music therapy as an alternative way of nursing intervention in clinical nursing process of caring female patients with breast cancer.

OBJECTIVETo explore the mechanisms of differentiation and development of pancreatic endocrine cells as well as pancreatic regeneration.

METHODSHuman embryonic pancreatic tissue at 7-14 weeks of gestation was collected. Diabetes mellitus rat model was induced with 65 mg/kg of streptozotocin. Insulin, glucagon, somatostatin, nestin, and cytokeratin 19 (CK19) of pancreatic tissues were observed by immunohistochemistry.

RESULTSAt 9 weeks of gestation, pancreatic epithelial cells began to co-express insulin, glucagon, somatostatin, and CK19 before migration. Islet cells gradually congregated along with the increase of aging, and at 14 weeks of gestation histological examination showed islet formation. At 12 weeks of gestation, nestin-positive cells could be seen in the pancreatic mesenchyme. During early embryogenesis, islet cells of pancreatic ducts co-expressed insulin, glucagon, and somatostatin. During pancreatic regeneration after damage, nestin expression of islet cells increased.

CONCLUSIONIn the early stage of embryogenesis, islet cells of primary pancreatic ducts can be differentiated to multipotential endocrine cells before migration. During tissue regeneration, pancreatic stem cells may differentiate and proliferate to form pancreatic islet.

OBJECTIVEThe aim of this study was to investigate the clinicopathological characteristics, effective treatment and prognosis in childhood and adolescent Hodgkin's lymphoma.

METHODSA total of 88 patients with childhood and adolescent Hodgkin's lymphoma were treated in the Cancer Hospital of CAMS from 1998 to 2005. The clinicopathological and follow-up data of the patients were retrospectively reviewed. The survival rate was calculated by Kaplan-Meier method and compared by log-rank test. COX multivariate prognosis analysis was performed.

RESULTSThe 2-year event-free survival rate of the 88 patients was 86.4%, the 5-year event-free survival rate was 61.4%, and the 5-year overall survival rate was 95.5%. Univariate analysis showed that the stage of disease (P = 0.033), "B" symptoms (P = 0.028), bulky disease (P = 0.007), splenomegaly (P = 0.050), LDH elevation (P = 0.020), chemotherapy regimen (P = 0.003) were prognostic factors in the 5-year event-free survival rate. Splenomegaly (P = 0.039), LDH elevation (P = 0.033), chemotherapy regimen (P = 0.008) were prognostic factors of 5-year overall survival rate. Multivariate analysis showed that chemotherapy regimen (P = 0.033), stage of disease (P = 0.023), LDH elevation (P = 0.008), "B" symptoms (P = 0.044), bulky disease (P = 0.009) were independent prognostic factors of 5-year event-free survival rate. The chemotherapy regimen (P = 0.012) and LDH elevation (P = 0.046) were independent prognostic factors of 5-year overall survival rate.

CONCLUSIONSThe non-ABVD chemotherapy regimen, stage IV disease, LDH elevation, associated with "B" symptoms and bulky disease are independent prognostic factors of 5-year event-free survival rate. LDH elevation and non-ABVD chemotherapy regimen are independent prognostic factors of 5-year overall survival rate.
